loadlofig fills the lofig pointed to by ptfig with the contents of a disk file called figname. The loading mode may be either 'A', then the entire content is parsed, or 'P' then only connectors and extrernal signals are loaded in memory, or 'C', that loads the "complement" of an already partially loaded cell in order to keep the same pointer when accessing the same file.The loadlofig(3) function in fact performs a call to a parser, chosen by the MBK_IN_LO(1) environment variable. The directories searched for the file are first the one sets by MBK_WORK_LIB(1) and then, in the described order, the ones set by MBK_CATA_LIB(1). See MBK_IN_LO(1), MBK_WORK_LIB(1), MBK_CATA_LIB(1) and mbkenv(3) for details.
